Figure 2. Assessment of peptide and peptide spectral matches for identified proteins across brain regions.
(a) The frequency of unique peptides for all proteins identified from frontal cortex. More than 80% proteins identified with more than 2 unique peptides. (b) The frequency of peptide spectral matches (PSM) for all the proteins identified in frontal cortex. More than 75% proteins identified with more than 6 PSM, and about 85% proteins identified with more than 2 PSM. (c) The frequency of unique peptides for all proteins identified from the anterior cingulate gyrus. About 90% proteins identified with more than 2 unique peptides. (d) The frequency of PSMs for all the proteins identified in anterior cingulate gyrus. More than 85% proteins identified with more than 6 PSM. Both unique and shared peptide PSMs were considered in the analysis.
